Compatible Samsung NP900X4D CMOS Battery

This DBTLAP lithium CMOS battery is designed for Samsung NP900X4D and 900X4D laptop motherboards. It serves as a direct replacement for the original RTC BIOS battery that maintains system time and firmware settings. The unit is tested before shipping to ensure reliable operation. It is a motherboard component, not a main laptop power battery.

For Builders Replacing a Dead RTC Cell

This part suits technicians and owners whose Samsung NP900X4D or 900X4D shows CMOS checksum errors, resets the clock on every boot, or loses BIOS configuration. It is not for users looking for a main rechargeable laptop battery pack to power the portable device. Buyers needing a different form factor, voltage, or connector for another laptop model should look elsewhere.

Lithium Chemistry Determines Fit

The lithium chemistry defines the voltage and physical profile required by the NP900X4D and 900X4D motherboard socket. Only a matching lithium coin cell will retain BIOS data correctly. Verify the original battery markings before ordering to confirm this specification aligns with the motherboard requirements.
